ISP: Comcast
Country of Residence: USA
When does the problem occur: Sporadically

I used to play using WiFi, but found that the latency ("lag") always got me killed in Titan EX. I've since switched to wired Ethernet and that issue went away.

However, while debugging I set up a monitoring system to ping Hyperion as well as a system located in the USA. (I do this sort of stuff for a living.)

The monitoring system I have is on wireless, so it's possible some of the loss is attributable to that. However, it's obvious there's connectivity issues to Hyperion in general. It's also possible that Comcast (or one of the links in between) is dropping pings deliberately, but that's entirely speculative.

In any case, I still see "lag" every so often, but it hasn't been a show-stopper recently. I don't have a ticket in with my ISP.

Hope this helps.
